DETACHABLE DRINKING BOWL.

Application filed May 9,

My invention relates to improvements in detachable drinking bowls with particular references to bowls of the type commonly used for watering cattle and horses.

The objects of my invention are to provide means for supporting and locking the bowl securely and with substantial rigidity in position for use, while allowing the bowl to be instantly released by the attendant, and preventing accidental release under pressure by the nose of the animal, or any manipulation of which the animal is capable; also to provide a quick detachable drinking bowl for stock having a locking device which requires manipulation by the thumb and finger of an attendant to adjust it to releasing position; also to provide a quick detachable bowl having interlocking members or engaging mem ers co-operating with the locking device to hold the bowl. in position with substantial rigidity and to support it against lateral pressure and prevent lateral movement of the bowl.

Figure 1 is a side elevation, partly in vertical section, showing a detachable drinking bowl embodying my invention.

Figure 2 is a plan view of the same with a portion of the bowl broken away.

Figure 3 is a front elevation of the bowl chamber and valve mechanism showing also a fragment of the bowl.

Figure 4 is a detail view, partly in side elevation and partlyin section, of the adjustable means for operating the valve and of the parts directly associated therewith.

'Likeparts are identified by the same reference characters tliruout the several views.

The bracket 1 is connected with a support, such for example, as the frame member or post 2, by clamping bolts 3 which pass thru the bracket flanges 1 and engage a clamping plate 5.

The bracket 1 is provided with a forwardly projecting arm 6 which carries a valve chamber 7 provided with cavities 8 and 9, and an outlet 10. The valve chamher 7 is provided with ports on each side communicating with the cavity 8, and adapted to receive a supply pipe 12, and an air chamber 13 composed of piping of the same diameter as the pipe 12, these parts being interchangeable, whereby the supply pipe may be connected on either side as may be most convenient. The top of the valve chamber is provided with a threaded aperture to receive a plug 15, or if desired to 1921. Serial No. 467,830.

receive a supply pipe in cases where the connection is to be made from above. This plug 15 or the end of the supply pipe forms a seatmg for a spring 17, the lower end of which bears upon the top of a puppet valve 18 seated in an aperture formed in a partition member 19 separating the cavities 8 and 9. The valve 18 is provided with a stem 20 projecting downwardly thru the bottom wall of the casing 7, whereby the valve may be operated from a nose piece as hereinafter described.

The bowl 22 is provided with a rear portion provided with a depending flange or rib 23 which seats in a correspondingly shaped groove formed in the bracket 1, which constitutes an open pivotal bearing for the flange 23. This flange 23 is preferably formed on a relatively narrow rearwardly extending portion 25 of the bowl, and the back wall of this portion has a flat surface at 26 seating against the bracket 1 with its upper margin in close proximity to an overhanging shoulder 2'? on the bracket. A locking key 28, preferably rectangular in cross section, extends downwardly thru a correspondingly shaped aperture in the neck (3, the downward movement of the key be? ing limited by a cross pin 29 in proximity to the top of the key.

At its lower end the key is formed with a flat face at 30 adapted to fit against the inner surface of the back wall 26 of the bowl. extension 25. The opposite surface 31 of the key is a beveled surface, whereby when the flange 23 is engaged in the pivot groove of the bracket and the outer margin of the bowl swung upwardly toward a horizontal position, the upper margin of the wall 26 may strike this beveled surface 31 and force the key upwardly until the wall- 26 passes beneath it, whereupon the key may drop by gravity and automatically lock the bowl in a horizontal position.

To release the bowl from the bracket 1 after it has been looked as above described, it is necessary to grasp the top of the key 28 with the thumb and finger and lift it vertically until the upper margin of the wall 26 may swing outwardly beneath it, the outer portion of the bowl swinging downwardly and the portion 31 immediately in front of the rib or flange 23 bearing upon the brackets in such a manner as to lift the flange 23 out of the groove following the initial pivotal movement of the bowl about an axis lying within the groove. This arrangement requires the operator to hold the outer margin of the bowl or outer portion of the bowl with one hand when releasing the key with the other hand, thereby preventing the bowl from dropping to the floor.

If it is desired to avoid spilling the contents of the bowl when removing it the latter may be held in a nearly horizontal position after releasing the key 28, the outer portion of the bowl being depressed sufliciently to allow the upper margin of the part 526 to pass from beneath the shoulder 27 and the lower margin of the key. The bowl may then be lifted bodily and moved forwardly to a point where the upper margin of the wall 26 may be received in the recess 35, in which position flange 23 may be swung across the bracket ledge supporting the portion 32 of the bowl to allow the bowl to be depressed and removed without tilting it sufficiently to spill the contents.

A nose piece 36 of ordinary type is supported near the bottom of the bowl by a lever 37 pivotally connected with the upper margin of the portion 25 of the bowl at 38, and having a working arm 39 projecting underneath the valve stem 20. an operating piece {L is connected with the lever arm 3%) and provided with a concave depression ll to receive the valve stem. This operating piece a0 is provided with a depending threaded post 42 screwed into an aperture in the arm 39 of the lever, a coiled spring 43 being interposed between the elbow eat and the arm 39 to prevent the member tO from accidentally swinging out of its normal po sition of engagement with the valve stem 20, and to also hold the piece 4:0 in engagement with the valve stem in case the screw threads should wear out or be stripped from the post 42 as to those threads which are normally in engagement with the working arm 39 of the lever.

The valve 18 is preferably formed of rubber, and whenever this valve becomes worn the operating piece may be adjusted vertically in the direction of the working arm 39 of the lever, thereby allowing the valve 18 to move downwardly to its seat. lVhen the valve is so badly worn that it no longer seats properly it may be easily removed by shutting off the water supply, and then removing the plug 15, whereupon the valve and its stem may be lifted out of the valve casing.

I preferably provide the portion of the bowl with depending flanges 45 for engagement with the respective sides of the bracket 1 at its hook shaped lower end. These flanges prevent the bowl from sliding laterally in the bracket groove which receives the pivot flange or member 23. Projections at} on the rear face of the wall 26 are also adapted to engage the respective sides of the bracket 1 near the top of the wall 10 and in co-operation with the flanges 45 to prevent the bowl from moving bodily in a lateral direction.

I claim 1. A drinking bowl for stock having a rear wall provided with a depending pivotal flange, in combination with a bracket provided with a groove to receive said flange, and a vertically moving locking key adapted to engage the inner surface of said wall near the upper margin of the bowl.

2. A drinking bowl for stock having a rear wall provided with a depending pivotal flange, in combination with a bracket provided with a groove to receive said flange, a

vertically moving locking key adapted to engage the inner surface of said wall near the upper margin of the bowl, said bracket having an overhanging portion to receive said key, and said key being non-rotatably mounted in said portion, and provided with a flat face to engage the wall of the bowl.

3. In a drinking bowl the combination with a bracket having a horizontal extending portion and a depending portion provided with a recess, of a drinking bowl having a rear wall and detachable pivotal connection with said depending portion and positioned in said recess, said recess providing a shoulder extending over and adjacent to the upper margin of said rear wall, and a latch extending through the upper portion of said bracket and abutting against the inner portion of said rear wall.
